DOOR CHECK AND CLOSER.

SPECIFICATION forming part of Letters Patent No. 446,548, dated February17, 1891. Application filed May 20, 1890. Serial No. 352,461. (Nomodel.)

To all whom it may concern:

Be it known that1,J OHNEDWARD MELLOR, a citizen of Great Britain,residing at New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Door Checks andClosers; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

My invention relates to doorchecks and door-closers; and it consists inthe construction and novel combination of parts, as will be hereinafterdescribed, and pointed out in the appended claim.

The annexed drawings, to which reference is made, fully illustrate myinvention, in which- Figure 1 represents a plan or top view of myimproved door check and doorcloser, showing the device in its normalposition, the door being closed. Fig. 2 is also a plan or top view ofthe same, showing the door open. Fig. 3 is a horizontal sectional viewof the cylinder and its connecting parts. Fig. a is an edge view of thebar B. Fig. 5 is a plan view of the casting or standard. Fig. 6 is anedge view of the same. Fig. 7 is a detail seetional view of one end ofthe bar B. Fig. 8 represents a front view of the cylinder, showing thecentral slot and lugs m m. Fig. 9 is a perspective sectional view of thebracket A, and Fig. 10 represents a side elevation of a portion of thecylinder having the standard attached.

Referring by letter to the accompanying drawings, A designates abracket, which is secured to the lintel A above the door, the shape ofthe longitudinal portion of the bracket in cross-section approximatingthe shape of a triangle the base of which is uppermost. The bracket Ahas angular ends which are provided with eyes, through which screwspass, after which they are passed into the lintel.

E is a cylinder, which is pivoted to a stand ard D, and is provided withan air-valve F, which is screwed onto the end of said cylin der.

F is an india rubber disk, which is held against the edge of thecylinder by the airvalve or cap F, which is provided with an an nularrow of nearly central]y-disposed air-inlets or small holes f.

H is a piston-head, which is secured to the end of the piston-rod G,lying within the cylinder E, and is constructed in the following manner:A metal disk a is first fitted on the inner end of the piston-rod G,said disk dfitting snugly the inner diameter of the cylinder. Then aleather washer t of slightly greater diameter is next fitted upon thepiston-rod and is forced against the metal disk a. A rubber washer cisnext fitted up against the leather washer b, said rubber washer bein gof slightly less diameter than the leather washer Z), so that the latterwill be held directly in contact with theinner peripheral surface ofsaidcylinder. Lastly, a metal disk d is placed against the rubber washerc on the piston-rod and is secured in place by a nut or the like, sothat the parts may be removed when it becomes necessary to remove eitheror any of them for repairs or for other cause. The standard D is in theshape of a flat angle-iron, which is provided in its vertical portionwith screw-holes, through which the securing-screws are passed into thedoor to fasten the standard thereto. The horizontal portion of thestandard is provided with a number of vertically-disposed bolt-holes 71,through either of which the securing and adjusting bolts i may be passedto adapt the check and closer to lintels of different thicknesses, nutskbeing employed to hold the bolts 2' in place. The cylinder E isprovided on the outer face of its inner headl with two paralleloutwardly-projecting lugs W'Lfli, arranged one over the other, with aspace between them for the reception of the end of the horizontal portion of the standard D, a bolt 1) being employed to secure said partstogether.

13 is a metal bar, which is provided at its ends with bosses q and 9',which project at right angles from said bar 13 in opposite directions.One endthatis, the outer end-of the bar B is provided on its boss q witha grooved friction-wheel 20, which is secured to the boss g by a bolt orscrew and revolves or works against the horizontal or longitudinalportion of the bracket A when the door is be ing opened and also whileit is automatically closing. The outer end of ihepiston-rod projectsthrough a centrally disposed hole 1: in the inner head of the cylinderEand is pivoted through its outer end to the metal bar 13 intermediate ofits ends at 5. The inner end of the bar B is pivoted to the standard at3. In this position the parts are as applied to a right-hand door. Toapply them to a lefthand door the outer end of the barB must bedisconnected from the standard D at the point 3 and connected thereto atthe point 4. The cylinder must be disconnected at the point 1 andconnected at the point 2 of the standard, and the piston-rod must beagain connected to the bar B, it having been previously disconnectedtherefrom.

The air valve or cap I is fitted to the end of the cylinder in theordinary way, and the india-rubber disk F, which is so constructed asnot to be impervious to air,but is of such quality of texture as toretard the ready passage of air, offers suihcient resistance to preventthe door from slamming to or violently shutting while in the act ofclosing, and thus insures a steady easy automatic closing action.'lhepiston-rod G is encircled by a coiled spring G, which preferablyfits snugly within the cylinder E and normally acts to force the pistonoutwardly, and thereby operate the piston rod, and consequently themetal bar to which it is connected.

Some doors are flush with the lintel, while others are considerablyrecessed. In the latter class of cases the cylinderis attached to aplate, as shown in Fig. 10, Where the adjusting-bolts are employed topermit the standard to be elongated, which obviates the necessity ofusing a block, as is commonly practiced in such cases.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is- V V The combination, with the cylinderhaving the attaching-lugs and the projectingpistonrod, spring,and'piston-head, of the standard having interchangeable attaching-lugs,the reversible metal bar provided with a friction- Wheel and detachablypivoted to the standard and to the projecting piston-rod, and theangular guide-bracket for engaging the Erie tion-wheel on said metalbar,substantially as specified.

In testimony whereof I affix my signature in plesence of two witnesses.

JOHN EDWARD MELLOR.
